Elmdene EN3-QSC-RD Surface Magnetic Contact - Grade 3 - Small - Plastic (White)

Fitted lots of these over the years. They are a tough contact, which I fit to doors where there is a risk of someone tampering. The internals are encapsulated, making them ideal for outward opening doors, or when moisture could be a problem. The curved shape makes them difficult to grip hence reducing the chance of them being removed. within the contact there is a metal section that reduces their susceptibility to being affected by any external magnets. One I fitted to a workshop door was hit by a fork lift truck. The door was wrecked but the contact still worked!
